What is the term for a systematic way of organizing and understanding observations?
theory
What is the term for a proposed relationship between two variables?
hypothesis
What is the term for anything which can be measured or described along a particular dimension?
variable
What is the term for a variable which can be measured across a continuum (e.g. weight, hours of sleep)?
continuous variable
What is the term for a variable with a fixed meaning or attribute (e.g. anxiety disorder, parental marital status)?
categorical variable
What is the term for labeling and describing the variables of interest?
operationalizing definitions
What are the five easy steps of research methods?
develop a theory based on observations
develop a hypothesis from the theory
design a research study
gather the data
analyze the data and report findings
What is the term used to describe a study that measures what it's supposed to measure? (e.g. eating snickers bar during exam doesn't necessarily measure hunger/exam performance)
validity
What is the term used to describe a study that gets consistent results over time?
reliability
What type of research focuses on systematic observation and exploring changes in variables of interest?
experimental method
What variable is manipulated by the experimenter?
independent variable
What variable is measured to assess any change in response to the manipulation?
dependent variable
What is the term for random subjects that represent the population as a whole?
subjects
What is the term for skewed samples that give results which don't generalize?
sampling bias
What is the term for the group that receives the special treatment in the experiment?
experimental group
What is the term for the group that receives all the same treatment except the independent variable to assess its impact?
control group
What is the term for a variable (other than the independent variable) which can impact the results? (e.g. time of day, lighting)
extraneous variable
What is the term for keeping research procedures constant to assure confidence when comparing results?
standardization
What is the term that describes the fact that expectations/expectancies can impact subjective experiences?
placebo effect
What is the term that describes the fact that subjects may behave in ways they think are expected of them? They respond to subtle or unintentional cues from the experimenter
demand characteristics
What is the term that describes people's tendency to give answers which are "correct" or "appropriate" and not necessarily true?
social desirability
What is the term that describes the ability to reasonably apply the results to other similar populations?
generalizability
What is the term that describes consistency in answers reflective of a patterned response answer in a set?
response set
What is the term that describes the fact that research expectations may impact the interpretation of results?
experimenter bias
What is the term for a study that controls for subject bias by limiting their knowledge?
single-blind study
What is the term for a study that controls for subjects and experimenter bias with limited knowledge for both?
double-blind study
What is the term for an in-depth study of an individual or small group that provides systematic observations? There is limited generalizability and these are susceptible to researcher bias.
case studies
What is the term for observation that looks at behavior in a natural environment? Report observations, can describe but not explain behavior.
naturalistic observation
What method allows for a large sample size and is often based on questionnaires and interviews?
survey method
What kind of study explores the relationship between two variables using a numerical value?
correlational study
What is the term that describes the fact that two variables are correlated only because each is causally related to a third variable?
third-variable correlation
What is the term for when group scores are added and divided by the number of scores?
mean
What is the term for the score that falls exactly in the middle of the scores?
median
What is the term for the most frequently occurring score?
mode
What is the term for how much individual scores vary?
standard deviation
What are seven of the APA ethical guidelines for research?
